Definitions

  • the following invention is directed to a stroller, and more particularly to a stroller which can conveniently collapse to a non-use position.
  • Collapsible strollers are well-known in the art.
  • the mechanism which allows the stroller to collapse is generally cumbersome and often requires the user to inconveniently unlock the mechanism and collapse the stroller. This becomes increasingly difficult if the operator has a physical condition, such as a bad back or is pregnant, which may limit the operator's agility.
  • the operating mechanisms of some conventional strollers with release bars are disadvantageous because items can get caught between the release bar and the handlebar, possibly pinching the operators' fingers. Further, the mechanisms with release bars generally add weight to the stroller and are cumbersome and difficult to actuate. They also suffer from having exposed mechanical parts which are subject to wear and increased friction.
  • the present invention is directed to a stroller that substantially obviates one or more of the disadvantages of the related art strollers.
  • An object of the present invention is to provide a stroller that allows an operator to easily collapse the stroller.
  • Another object of the present invention is to provide a stroller that allows an operator to collapse the stroller conveniently and without having to bend over and reach down.
  • Yet another object of the present invention is to provide a stroller with a mechanism that allows easy collapse of the stroller.
  • the present invention relates to a stroller, and more particularly to a collapsible stroller with an improved mechanism for folding the stroller.
  • FIGS 1A, 1B, and 2 show a preferred embodiment of a stroller 100 in accordance with the present invention.
  • the stroller generally comprises a frame 102 having a handle portion 104.
  • the handle portion also includes a gripping portion 106.
  • the stroller includes a passenger support 108 best seen in Figure 2, that is used to hold a child.
  • a suitable number of wheels 110 to allow easy transport are provided.
  • the preferred stroller 100 also includes at least one locking device 112. This locking device allows the stroller to collapse from an extended position as shown in Figures 1A and 1B to a collapsed position.
  • This improved stroller includes at least one actuating assembly 114 which actuates at least one of the locking devices 112.
  • the preferred mechanism includes an actuating assembly 114 which comprises a stationary member 202 and an actuator 204.
  • the actuator 204 is connected to a rod 206, and the rod 206 is connected to a slidable catch 208 of the locking device 112.
  • the locking device 112 includes a spring (not shown) to bias the slidable catch 208 into a latching position. Since the rod 206 is connected to the slidable catch 208 and the actuator 204, the actuator 204 is biased into the stationary member 202 when the stroller 100 is in the extended configuration.
  • the specific structural details of the locking device 112 can be gathered from Assignee's prior patent, U.S. Patent No. 5,454,584, issued on October 3, 1995, which is incorporated by reference.
  • One feature of the present invention is to allow an operator to more easily collapse the stroller.
  • the operator By placing the actuator 204 in a location that is vertically higher than the location of the slidable catch 208, the operator does not have to lean forward and bend over as much to release the locking device 112 to collapse the stroller since the actuator 204 is in a more convenient location.
  • This feature is particularly important if the operator has a physical condition that may make leaning forward or bending over difficult, for example: a bad back or pregnancy.
  • This feature is also important if the stroller of the present invention is a dual stroller. That is, if the stroller is of the type in which two passengers ride side by side.
  • Figure 3 shows an enlarged isometric view of the locking device 112 and rod 206.
  • rod 206 runs generally parallel to arm 304.
  • the rod 206 preferably runs through hinge 302 and in between arm 304 and leg 306.
  • the rod 206 terminates in a first end 308.
  • the first end 308 preferably includes a bend or hook 310 that cooperates with an aperture 312 formed on the slidable catch 208.
  • the rod 206 terminates in a second end 422, preferably connected to actuator 204 as shown in Figures 4A and 4B.
  • Figures 4A, 4B, 5A, and 5B show the components attached at the other end of rod 206.
  • a stationary member 202 is rigidly connected to handle portion 104 by a series of screws 402 and 404.
  • the stationary member 202 includes a forward portion 408 that includes 3 rod entry portion 410.
  • the forward portion 408 of the stationary member 202 is open as shown in Figure 5B. As rod 206 is pulled by actuator 204, the open forward portion 408 allows the rod 206 to move freely into the stationary member 202.
  • the stationary member 202 also has a top portion 412 that is adjacent to the handle portion 104 and a side portion 406.
  • the top portion 412 preferably has at least one hole 414 for a fastener 402 or 404.
  • the rear and central portions of the stationary member include at least one guide member 420.
  • the guide member 420 comprises a T-slot 422.
  • the interior of the stationary member 202 is generally hollow and designed to accommodate the actuator 204 as shown in Figures 4A and 4B.
  • the actuator 204 includes a socket 428 which is engaged by the end of the rod 206.
  • the actuator 204 shown in greater detail in Figures 6-10, includes a finger pull 602 and a beam portion 604.
  • the follower 606 has at least one groove 614.
  • follower 606 has two grooves 614.
  • the forward end of the beam portion 604 includes a rod receiving portion 608.
  • the preferred embodiment contemplates the use of an aperture 612 formed vertically on the forward end of beam portion 604 to receive the other end 322 (see Figures 4A and 4B) of rod 206.
  • the beam portion 604 also includes an elongated slot 910, best shown in Figures 9 and 10.
  • Fastener 402 connects the stationary member 202 to the handle portion 104.
  • the elongated slot 910 is sized to allow the actuator 204 to move along the stationary member 202 even though fastener 402 is mounted through the slot 910 as shown in Figures 4A and 4B.
  • the stationary member 202 is shown as mounted on to handle portion 104 with fastener 404 shown.
  • the preferred embodiment of the T-slot 422 is shown.
  • the follower 606 of the actuator 204 is shown mounted in T-slot 422.
  • the preferred embodiment of the T-slot includes at least one guide member 420 that engages a groove 614 on the follower 606 of the actuator 204.
  • the follower 606 rests on guide members 420.
  • the height of the T-slot 422 is high enough both to allow the follower 606 to move along the guide members 420 of the stationary member 202 and to accommodate the head of fastener 404 as shown in Figure 5A and 5B.
  • the beam portion 604 of the actuator 204 extends from the finger pull 602.
  • the stationary member 202 receives the beam portion 604.
  • the second end 318 of the rod 206 extends into the forward portion 408 of the stationary member 202 and engages the aperture 612 of the rod receiving portion 608 of the actuator 204.
  • the operator moves the actuator 204.
  • the operator engages the finger pull 602 of the actuator 204.
  • the rod 206 is correspondingly moved to the right due to its connection with the actuator 204.
  • the forward portion 408 of the stationary member 202 has an opening and hollow portion that provides clearance for the rod 206 as it is pulled into the stationary member 202 by the movement of the actuator 204.
  • the rod 206 moves due to the movement of the actuator 204. Since the first end 308 of the rod 206 is connected to the slidable catch 208, the movement of the actuator 204 moves the slidable catch 208. As the slidable catch 208 is moved, the locking device 112 is released and the stroller 100 may be collapsed.
  • the preferred embodiment of the rod is shown.
  • the first end 308 of rod 206 includes a bend or hook 310 as shown in Figure 12.
  • the rod 206 has a second end 422 with at least one bend 424.
  • the second end 422 has two bends 424 and 426. The two bends 424 and 426 are shown in Figure 11.
  • rod 206 has a longitudinal axis.
  • Figure 13 is a view from the perspective of looking along the longitudinal axis of rod 206. As shown in Figure 13, the first end 308 and the second end 422 of rod 206 are skewed and are formed at an angle with respect to one another.
  • While the preferred material for the stationary member and the actuator is plastic, metal or any suitable material may be used. While the preferred material for the rod is plastic, metal or any suitable material may be used.
